The Lost Child: A Mother's Story unfolds as a poignant narrative intertwining the life of Julie Myerson's distressed family with the historical account of Mary Yelloly, a Regency era girl whose early death left behind a legacy through her watercolors. Julie's painstaking research into Mary's life is abruptly mirrored in her personal ordeal when her teenage son falls into the clutches of drug addiction, leading to his exclusion from the family home. This heartrending parallel conveys the universal agony of maternal love facing the abyss of loss, and the enduring question of what remains of us in memory and history.
